FlowTechs Exterminator Series 2.5'' H-Pipes, X-Pipes and Starter Tubes are the perfect beginning to building a free flowing high performance exhaust system for your off-road Mustang! All units are manufactured using high quality aluminized 16 gauge steel and are mandrel bent to fit your OE shorty-style ball and socket collector headers. Designed to fit your OE-exhaust hanger locations to make installation a breeze! The perfect choice for your Drag Race, Road Race, Time Trial/Attack, SOLO Racing or anyone off-road that needs a high flow exhaust without catalytic converters!

H-PipesWith their larger than factory diameter these kits are perfect for enthusiasts looking for an off-road/racing H-pipe. These pipes maintain your low end torque while offering you a free flowing size and construction for more power in the midrange up to your shift point!

X-PipesDesigned to bolt on quickly and add up to 12 horsepower! Manufactured to free up horsepower by reducing the effect of a V8 engine's out-of-sync firing order, occurring when two cylinders on the same bank fire within 90° of each other and cause a crowded condition in collector and exhaust pipes. X-pipes also promote balancing and equalizing, which decreases negative harmonics and increases exhaust velocity making you more power! These off-road/racing X-pipes fit manual transmissions applications only.

Starter TubesFlowTech's 2.5'' diameter aluminized starter tubes give you a larger diameter choice but can still attach to any OE X and-H-style pipe on your 1986-1993 Mustang. With these pre-formed OE style tubes you can choose the sound style and tailpipe configuration you want!
